Explanations:The question pertains to the major rubber-producing state in India. Rubber is a crucial natural resource used in various industries, including automotive, construction, and manufacturing. In India, rubber is primarily cultivated in the southern states, with Kerala being the leading producer.
Kerala's geographical location and climate make it highly suitable for rubber cultivation. The state has a tropical climate with high humidity and abundant rainfall, which are ideal conditions for rubber trees. The soil in Kerala is also rich in nutrients, further enhancing the growth of rubber trees. These factors contribute to the high yield and quality of rubber produced in the state.
Other states like Tamil Nadu and Maharashtra also produce rubber, but their production is not as significant as that of Kerala. Tamil Nadu has some rubber plantations, but the climatic conditions are not as favorable as those in Kerala. Similarly, Maharashtra's climate is not as conducive to rubber cultivation, and the state's production is minimal compared to Kerala.
Therefore, about 90% of India's rubber demand is met by Kerala, making it the correct answer to the question. Understanding the geographical and climatic factors that influence the cultivation of rubber is essential to comprehending why Kerala is the leading producer in India.
